Person got tricked into dying multiple times at level 1, without realizing he loses stats each time he dies. As a result, he has to kill a bunch of chicken to regain his lost status points.
Honestly, I don't recommend that reading Ark. The story is mediocre at best but the translation is garbage. Both Legendary Moonlight Sculptor and Overgeared have almost the same moneygrubbing MC and initial setup as Ark but they are both better.
